1. I want the extended cab... maybe the 4 door? I'm afraid I'm not sure what the difference is. Was there an extended cab 2 door?

2.Also, I'm not sure if I'm looking for an 02, or an 03. What was the last year of the horizontal headlights? I'm not a huge fan of the slanted eyes look. But I can't remember if the last year of of the headlights I want was 02, or 03.

3. Is there anything in particular that I should watch out for when buying one? Factory defects, commonly known flaws, etc.

4. What were all the colors available? I think I've seen red, white, black, and tan. This would be chevy colors only, as I'm not looking to buy a GMC truck.

5. What was the highest options package? Want to make sure I get that.

6. Was there much of a difference in the engines? All I know is that the 5.3L was available. Did they have the 6.0L back then, or was it something else? And when it comes to modding it a gas mileage, what would be the differences in the engines? I'd like to give it a power bump but I don't want to get 10mpg.

Thanks in advance! I'm sure I'll pop back in here with more questions.

Thanks! Anyone have the quick and dirty on power mods for the 5.3L, that won't hurt mpg? Exhaust obviously, maybe some kind of mild cam? Even something like better rocker arms? A tune? What's everything I can do that would boost power but not hurt MPG?

instrument clusters, knock sensor, intake gaskets, rear main seals leak, sometime the pump in the transfer case rubs though the case housing, other then that not much, i have a 2002 burb with 225k ive had 4 years i only done the intake gaskets knock sensors, vavle cover, and valley pan gasket, water pump, i just rebuilt the front end on it with all new ball joints upper control arms gear box inner and outter tie rods, pit and idler arm and schocks all the way around what a differance it made

now i was given in january a 2000 thaoe with 5.3 had 369k miles on it with orginal motor and trans it was leaking like crazy from everywhere and trans was shot idid a motor and trans swap with 150k used units and now it purring again

If by chance you are looking for a truck, I found this MINT, 2000 SLT w/ an ARE topper painted to match. One owner ( retired) & garaged. I REALLY considered this, when I was deciding on my (just bought), 2005 Yukon XL , SLT.

Sarasota, Fl. truck.... I could call him if he still wants to sell it ($6,600?) .. I think it has only 98,000 or 110,000 miles.... ( somewhere around that)

There are badges at the bottom of the C pillar(B pillar if its a regular cab).

Thanks! I'll look there to make sure its the right trim level. Anyone happen to know what the real differences were between the LT and the other trim levels? Better sound system, automatic windows, stuff like that?

Yes... stuff like that. ( Buying used, you are beholden to what options the original buyer requested)

I could assume, you see if the seats are power, then there will be more options.

When it comes to the exhaust manifolds that would be on an 02, are shorty headers really any improvement? The factory exhaust manifolds on the LS look like they already are shorty headers. So I question whether a good set like kooks would actually be worth the money. I'm not really into long tubes, as I don't like losing the work space.

I would imagine headers by themselves wouldn't yield a noticeable difference in power, no matter if they are shorties or long tubes. Most people I have seen on forums that have headers use long tubes. But those people also have more mods (heads, cam, supercharger, etc.) & get the combination tuned.
